To .455 whom may concern.-

Be it, known that 1, JOHN T. CHENEY, e. ciiizen or" the Unitezi States, and eresideni; of Swerthmore, county of Dela-Were, State Dennsyivenie, have invented cezcein Kmprovemenis in FioorCoverings, of which the foiiowing is a specification.

Che invention relates to certain improve ments in floor coverings of the oil oiotil type.

One object of the invention is to make floor fJOK (fillg having a cit base and e linseed oil and fiiiei" composition "wearing A further objectof the invention is co provide means for mechanically iioidicg the Wearing surface iim iy to the felt base. k

A. stiii fixi' ciior obgect of the mv. iconto relieve the felt from pressure so as 30 present of the wearing sun face to any considerable extent. w

Cihese objects I attain in she foiiowiiig manner. reference being bad 53o the fiCCQHb s in which:

and "2' are view; showing the base 522W 253 an under-a; perforziion and the metea a. forced, into 0 perforations.

Referring to Figs. 1, i2 and 3 of ihe diteW- iHgS, l a felt base which is impregnated Wiii'i 1- semisoiicibi flows-materiel. This felt base is made of dry felt, pz'efci'ebiy ,i'om cotton regs, cation Waste, or: other suitable metci'iei. and the felt is sawmieii with a substance which Wiil thorougeiy impyeg' note it, nmking it piiobie and. proof against moisture.

The substance E prefer to use consists oi: pei'coieum flux oil, end; a. residual pitch deriveii from aspheitic or semi-asphaitic base oiis, out other hydrocarbons ma 1 he used, if desreii. Tile sziziceiei is heetc and pieced? in a saturating ketizie so as to allow it to pass into the felt. During the setumtiiigprocess,

the material will thoroughly impregnate the felt. The felt is then eiiowe to coci and is perforated, as of; The perforations may. be 01": any shape and size desired; and. may be straight, as shown in Figs. 1 and 2, or may be undercut as shown in Figs. 6 enci Y, or the perforationsmay bomede by punetmfiiig the back 1", as at- 2, Fig. 5, so as to mm a i'ougiieneci surface to which the Wearing sue face v ii readiiy adhere.

3 is the Wearing surface of 24, linsoeci oil composition, in the resent instance cczzeie ing of linseed oii em afiiier-of floured woe-(i pulp. This surface is applied to the 1 in the same maner that linoleum is fipiibii to a surlap base. Pressure is than e-gii'biiee o es "to force" the surface con w "ciii'ough the perforations in the l" the same time reducing the thicimess K it base, as shown in 2. Fig. 1 e3: e felt base before being retiuceo. by p sure and also shows she Wearing scrim; foi'e being compresses}.

i have found it (iiiiicuit to secure surface "to the felt base by simply pi" mg the wearing surface onto the base, as 12'; 1'

iiebie to se arate due to the neciiiier Chit-1 actor of the saturating composiion for fiiie fihe fact that the felt base alone Wiii yieicl.

under pressure, whereas the material of the Wearing sm'face W111 sustain its load end else has a tendency to return to ivts noemai coiidition after pressure is eppiieoi, SOthZt the projecting of the surface materiei into the pezrforafiions not cniy unites the ewe surfeces, but also acts as a support for the Wee?- ing surface.

in some instances, as iiiustratedizi Fig; 42., an asphait binder may be uscci between the wearing surface and the felt base, end ibis binder will cause the two mafiei'iais iro adhere one to the other, particularly as she him.

may extend into the perforations between the projections and the walls of the perforations, as clearly shown in Fig. i.

I claim 1. A floor covering consisting of a perforated felt base and a compositlon wearing surface having projections extending into the perforations of the base.

2 The combination of a perforated felt base, said perforations being undercut, and a iinseedoil Composition wearing surface hav ing projections extending into the undercut perforations of the base.

3. The combination in a floor coverin of a felt base saturated with a semi-solid, ituminous material and having perforations, and a cork com osition wearing surface applied to the fe t base by pressure so as to cause the materal of the wearing surface to be projected into the erforations.

In witness whereof aflix my si ature.
